'BOBBIN-HOLDING' MEANS.

Application filed June 29,

T 0 (ZZZ whom it may concern Be it known that 1, WILLIAM P. WOOD, acitizen of the United States, residing at 34 Brook St, Pawtucket', inthe county of Providence and State oil? Rhode Island, have inventedcertain new and useful Improvements in Bobbin-l-Iolding Means; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in bobbin holding means for loomshuttles.

Bobbins used in loom shuttles, and more particularly those used in theshuttles of weft replenishing looms, are made of wood and are usuallyformed with a projection at the butt having ribs or shoulders which areengaged by a tongue on a bobbin catch carried by the shuttle body. lViththis construction, the wooden ribs are frequently split oli by theconstant hammering due to the travel of the shuttle back and forth andthe sudden starting and stopping of: the shuttle, thus delaying theweaving and rendering the bobbin unfit for further use. Considerableloss is occasioned in this way and various kinds of bobbin holders havebeen devised, but they have not been success ful in preventing injury tothe bobbins.

The object this invention is to prevent such wastage of bobbins and lossof time in the weaving by providing improved bobbin holdin means -formore securely holding the bobbin in the shuttle during the weaving.

To this end the bobbin is held in the shut tle by means of interlockingmetallic holding devices, one or more members of which are on theshuttle and one or more cooperating members of which are on the bobbin.The holding devices preferably comprise spurs or fingers arranged to litwithin metallic or reinforced sockets, and the spurs are preferablyformed on a spring catch plate secured to the shuttle, while thereiniorced sockets are preferably formed by embedded metallic bushingsin the butt of the bobbin, since this enables the strain on the bobbinmember to be more evenly distrib uted and more effectively withstood.

Referring to the drawings, Figure l is a view'partly in side-elevationand partly in Specification of Letters Patent. Patented July 26, 1921.

1918. Serial No. 242,673.

longitudinalsectionof a portion of a shuttle, with a bobbin occupyingits normal or operative position therein, and showing a preferred formor" the lnvention; Fig. 2 IS a similar view showing the bobbinspindleelevated to release the bobbin; Fig.3 is a bot spindle through which thepivot pin passes has two angularly disposed positioning faces E and F onits under side, adapted to cooperate with a spring member to hold thebobbin spindle in its two extreme positions; one being the normal oroperative position, and the otherbeing the bobbin receiving andreleasing position. The parts so far described are of usualconstruction.

The bobbin holding means comprises two fingers or spurs 7 projectingupwardly from a spring catch plate 5 which is secured to the shuttle bythe screw 6, and which may also form the spring member cooperating withthe spindle positioning "faces E and F. The spursare arranged to engagereinforced sockets 11 formed by inserting metallicbushings 10 inholesbored in a longitudlnal tongue 8 which extends'diametri'callyacross the butt end of the bobbin G, and is formed with two parallelfiat surfaces 9. The tongue is of sufiicient thickness to allow thecentral longitudinal opening H in the bobbin to continue therethrough.The socket holes are bored transversely through the tongue at'rightangles to the surface 9,

one at each side of the central. opening H V which receives the spindleB. The metallic bushings are inserted in the holes and the ends arerolled over on to the opposite fiat surfaces 9 of the tongue so as tohold the bushings securely in place, and also strengthen the tongueaboutthe bushings. Reinforced sockets are thus formed which ily beengaged with the spurs oft-he catch.

The bobbin is first placed on the spindle while the latter is in itsreceiving position, I

as shown in Fig. 2, and as it is swung downwardl toward its operativeposition, the spurs on the bobbin catch enter the sockets 11 in thetongue. Inasmuch as the sockets extend through the tongue, the spurs onthe bobbin catch may enter them from whichever yarn carried by thebobbin.

When the spindle and bobbin are finally positioned, as shown in Fig. 1,the spurs 7 project practically their entire length into the sockets andsecurely hold the bobbin against longitudinal displacement on thespindle, and also position it with the 'teeler hole I in proper relationto the replenish ing mechanism. The strain resulting from the suddenstopping of the shuttle during the weaving is resisted by the bushingswhich are firmly seated within the wooden tongue of the bobbin, so thatthey will effectively resist the strains and shocks to which they aresubjected without danger of breaking the tongue or of becoming detaChedtherefrom.

While the invention has been herein described and illustrated by thedrawings in accordance with what is now considered to bethepreferred'embodimentthereoi, it will be understood that changes in theform and arrangement may be made without departin from the spirit andscope of the claims,

Ilaving described the invention, what is clanned 1s 1. In a shuttle, thecombination with the bobbin and the bobbin spindle, of a longitudinaltongue at the butt end of the bobbin having a socket extendingtransversely therethrough, and a spur on the shuttle body adapted toengage said socket when the bobbin is inserted to lock the bobbinagainst longitudinal displacement or turning on the; bobbin spindle.

2. In a shuttle, the combination with the bobbin and the bobbin spindle,of a longi tudinal tongue projecting from the butt end of the bobbinhaving sockets extending transversely therethrough, and bobbin. holdingmeans on the shuttle'body adapted to codperate with said sockets to holdsaid bobbin against longitudinal displacement in the shuttle andpositively prevent the bobbin from turning on the bobbin spindle.

3; In a shuttle, the combination with the bobbin and the bobbin spindle,of a longitudinal tongue at the butt end of the bobbin having atransverse recess therein, a bushing in said recess, and a bobbin catchon the shuttle body having a spur adapted to enter said bushing when thebobbin is inserted in the shuttle to lock the bobbin againstlongitudinal displacement or turning on the bobbin spindle. a

4:. In a shuttle, the combination with the bobbin and the bobbinspindle, of a longitudinaltongue at the butt end of the bobbin havingreinforced sockets extending transversely therethrough, a bobbin catchon the shuttle body, and spurs projecting from said bobbin catch adaptedto enter said sockets to lock the bobbin against longitudinaldisplacement or turning on the bobbin spindle.

'5. In a shuttle, the combination with the .bobbin and the bobbinspindle, of a longitudinal tongue at the butt end of the bobbin havingrecesses extending transversely therethrough, bushings in said recesses,a plate secured at one end of the shuttle body, and spurs projectingfrom the opposite end of said plate and adapted to enter said bushingswhen the bobbin is inserted in the shuttle to lock the bobbin againstthe longitudinal dis placement or turning on the bobbin spindle.

6. In a shuttle, the combination with the bobbin and a pivotedbobbinspindle having positioning faces at its pivoted end, 01 a tongueprojecting longitudinally from the butt-of the bobbin and having holesextending transversely therethrough, bushings in said holes, a springplate secured at one end to the shuttle body and adapted to cooperatewith said positioning faces to hold said bobbin spindle in operative andinoperative positions, and spurs on said plate to engage said bushingswhen said bobbin spindle is swung into operative position to lock thebobbin against longitudinal displacen'ient or turning on the bobbinspindle.

7. The combination in a shuttle having a pivoted bobbin spindle withpositioning faces formed at its pivoted end, of bobbin catch comprisinga spring plate secured at one end to the shuttle body, and adapted tocooperate with said positioning faces to hold said spindle in twopositions, spurs on said plate, and a bobbin adapted to be inserted onsaid spindle when said spindle is in one position and provided withsockets in the butt thereof adapted to be engaged by said spurs when thespindle is in the other position to lock said bobbin against longitudinal displacement or turning on said spindle. 1

8. A wooden shuttle bobbin having a tongue across its buttlend providedwith reinforced sockets extending transversely therethrough and adaptedto be engaged by bobbin holding prongs on a shuttle.

9. A wooden shuttle bobbin having a tongue across its butt end providedwith two transverse holes, and bushings in the holes having their endsrolled over theitaces of the tongue.
